Polishing Tips
If the specimen material is water reactive, ethylene glycol can be used as a substitute for water, however
the polishing time may need to be extended.
Buffer water can be used to prevent reaction with water sensitive materials. Buffer solutions are adjusted
to a specific pH and a pH solution of 7.0 (neutral) is recommended for vibratory polishing.
Polishing steps and times will vary depending on the specimen material.
a. Run through a polishing sequence and monitor the progress at 15 to 30 minute intervals.
b. Remove the specimens from the polisher.
c. Clean and dry them.
d. Examine the specimen under a microscope.
e. Adjust the polishing sequence as needed. Some polishing times will exceed one hour.
f.
Keep a record of successful preparation and polishing sequences for future applications.
